From what I have observed, people in international F tend to dress much more casually. ..e.g. Johnnie Depp in AF, FC in torn jeans and tee-shirt last year. Some will opt to change into the P.J.'s offered in international FC right before take-off.
If you have a confirmed FC class seat, wear whatever is comfortable. I would exclude shorts and tank-tops.
